s claim.l (c1. ros-'n This invention relates to improvements in shingles, particularly designed to be used as a roofing or wall covering unit, the butt ofthe shingle or that portion exposed to the weather being of porcelain-enamel construction or other suitable metal such as brass, bronze, yellow metal, copper, white metal, and .acid-proof and other corrosion-resisting alloys. The enamel may be flexible if desired.

According to the present invention, a shingle is provided with a porcelain-enamel or foliated noncorrosive metal butt fixed to a base of pliant composition impervious to water, and also re' sistant to solar heat.

Also, according to the present invention a dependable and highly efcient shingle is provided for use in conjunction with roofs and walls in all types of structures where a roof or wall"of this type may be applicable, and the roof or wall or both may be made to congrue with the sthetic or artistic discernment of a builder or owner.

Various further and also various more specic objects, features, and advantages will more clearly appear from the detailed description given below taken in connection with the accompanying drawing which forms a part of this specification.

The invention consists in such novel features, arrangement and combination of parts and methods as may be shown, described and claimed in connectionvwith the embodiment of the invention herein disclosed by way of example only.

Constructional examples of the invention are illustrated in the figures, in which:-

Fig. 1 is a top plan view of a shingle unit embodying my invention.

Fig. 2 is a side or edge elevation of a modified form of a shingle, the reinforcing wire being omitted, otherwise the construction is the same vas that shown in Fig. 1.

Fig. 3 is a fragmentary side or edge sectional view of another modified form'of a shingle on a larger scale, showing the same provided with a reinforcing wire, and'also a reinforcing fabric over a portion of the base that is bent back upon itself to form the sealing means for the joint formed by the butt and the base. y

Fig. 4 is a fragmentary plan view of the butt detached from the base to show the laterally disposed notches therein.

Fig. 5 is a perspective view of the reinforcing element detached from the. shinglejproper and showing how it may be constructed.

In the drawing like characters of reference lndicate corresponding parts in the several ngures.

Referring to Fig. 1 illustrating a shingle, the shingle base 10 which in these illustrations is shown as a strip of iiexible impervious water resisting material is exed or bent over an enameled butt l1, and cemented or otherwise secured or attached thereto as at 12,. A reinforcing wire,

rod, cord or rope 13 is positioned transversally in the loop formed in the base substantially as shown, and the base is then bent back upon itself, and the loop thus formed is secured in any suitable manner as by cementin'g". The reinforcing element 13 may be bent over and under the base and secured in any suitable practical manner. The` ridge, protuberance or projection 14 formed by the bending of the ba'se upon itself forms one of the elements of the interlocking instrumentalities hereinafter described.

The butt of the shingle is provided with a ledge l5v that may extend transverse oi the shingle base, and may be provided with spines; spurs, spikes or other suitably pointed elements 16 and 17 that may engage under the ridge or protuberance formed on the base.

Adjacent the ledge 15 there is provided a gap or trench 18, this gap or trench is formed by stopping short the base l0 in proximity to the ledge, and has a depth equal to the mean thickness of two folds of the base that forms the ridge or protuberance.

The spines are adapted and arranged to engage in the ridge or under same, and forms with the ridge the other member of the interlocking instrumentality when the shingles are imbricated in the usual well known manner.

The wire reinforcing member is provided'to prevent fracture of the ridge that might be caused by the engagement therein or therewith, and also to prevent the ridge from becoming detached from the butt and thus allowing the water to seep into and under the ridge and percolate through the joint formed by the base and the butt that is sealed under the ridge. The shingle butt is also provided with laterally positioned notches, holes or apertures 19 and 20 to allow for the passage of nails therethrough in securing the shingles, the same being provided to prevent fracture of the enamel or metal butt in the process of attaching the shingles to a roof or wall.

A layer of fabric 21 may be employed to reinforce the ridge or protuberance if desired.

While the invention has been described in detail with respect to certain particular preferred examples which gives satisfactory results, it will be understood by those skilled in the art after understanding the invention that various changes and modications may be made without departing from the spirit and scope of the invention, and it is intended therefore in the appended claims to cover all such changes and modifications.

What I claimlas my invention and desire to secure by Letters Patent is:-

1. A shingle comprising: a exible base with an enameled butt, the base bent upon itself to form two loops, one of the said loops having mounted and sealed therein an end portion of the butt, the butt being attached to the base throughout at least a major portion of its length, a ledge integrally formed on the butt having spines associated therewith, a reinforcing means interposed in the other loop and cooperating with the base whereby the base is strengthened at that portion wherein the loops are formed.

2.`A shingle comprising: a exible base with a flexible enameled butt, the base bent upon itself to form two loops, one of the said loops having mounted and sealed therein an end portion of the butt, the end portion of the butt having laterally disposed notchesI therein, the butt being attached to the base throughout at least a major portion of its length, a ledge on the butt having spines attached thereto, and a metallic reinforcing element in the other loop and cooperating with the base whereby the base is strengthened at the portion of the base having loops formed therein.

3. A shingle comprising: a flexible base with an enameled butt, the base bent upon itself to form a plurality of loops, one of the said loops having mounted and sealed therein an end portion of the butt, the said end portion being laterally notched, the" butt being attached to the base throughout the major portion of its length, the butt also being provided with a ledge having spines spaced thereon, the other loop cooperating with the base, and means whereby the loops are maintained in eective relationship.

4. A shingle comprising: a flexible base with an enameled butt, the base bent upon itself to form two loops, one of the said loops having mounted and sealed therein an end portion of the butt, the said end portion having laterally positioned apertures therein, the butt being attached to the base throughout a major portion of its length, the butt also being provided with a ledge having a plurality of inwardly directedA spines therealong, a reinforcing fabric in the loops cooperating with the base whereby the base is strengthened at that portion wherein the loops are formed.

5. A shingle comprising: a pliant base exed upon itself, having attached thereto an enameled butt which forms with the base a joint sealed under and by the nexed portion of the base; a

reinforcing member transverse of the base, interpositioned between a exed portion of the base, and extending over edgeportions of, and under the base, notches laterally positioned in the butt,

positioned under the flexed sealing portion of the base; a. ledge on the butt; and spear points operatively associated with the ledge.

6. A shingle as defined by claim 5 further characterized in having a gap positioned between the ledge on the butt and the end of the base.
